[REG : 5.12 -> 5.15] Automated testing with Ranorex is broken with Qt 5.15.0

Automate testing tool, Ranorex is no longer able to properly create the object tree, and the few objects that are still detected, don't have any usable attributes (e.g. the "objectName" of a window is not detected anymore).

Buttons are still detectable, but neither texts nor attributes (e.g. IDs) are found.
Ranorex also "misuses" the accessibility features of Qt for its object detection.
See the reference images attached.
